samba - Nov 2003 - Newbie problem

good evening ...

i've mangaged to install a samba 2.2.3a server on Suse 7.0.
i've also managed to access the server with swat ..getting startet and
able
to browse my  shares with my windows xp system.
but i'm not able to mount any XP-share on my linuy machine over "mount
-t
smbfs -o user=USER,password=PWD //XP-machine/SHARE /linux-dir"

i got an error:
"mount: wrong fs type, bad option, bad superblock on //XP-machine/SHARE,
or too many mounted file systems"

before i got xp it i funtioned under win2k pro with samba 2.2.2...
does anyone have a solution for this problem ...

simple
workgroup

I'm trying to set up a Samba server following "Using Samba" pretty
religiously. I have compiled and installed version 3.0. Everything 
works pretty much as expected until I try to make a Windows XP client a 
domain member. Then when I put  in root in the Name Change dialog, it 
get a user name could not be found error. But the XP client has no 
trouble with root as a user name in workgroup mode.

I would really appreciate a clue as to what the problem is.
